It might improve net efficiency (and possibly allow servers to
precompute information or ignore these headers if they don't care) to
package together those things that are configuration specific (accept,
accept-encoding, accept-charset, accept-language and user-agent:) and
send them by reference, e.g.,

the client sends:


where NNNNNNNNNNNNNN is the MD5 of the omitted headers; the server
sends back an error return if it actually needs the fields.

This would be useful independent of whether the connection remains
open: even if the connection closes, the information might affect a
cache choice; even if the connection remains open, a proxy might want
to send different header information when proxying for different

(Clearly this would be in 1.1; if HTTP were recast as ILU or CORBA, it
would be done as a client object that the server could interrogate.)
